Answer:
1.27 moles (3 s.f.)
Explanation:
Mole ratio of water: C6H14
= 14:2
= 7:1
This means that to produce 7 moles of water, 1 mole of C6H14 is needed. Or 1/7 mole of C6H14 is needed to produce 1 mole of water. So if you need 8.86 moles of water, 8.86(1/7) moles of C6H14 is needed.
For 8.86mol of water, moles of C6H14 needed
= 8.86/7
= 1.27 moles (3 s.f.)
